Setting a Loopback for an Ethernet Interface

You can set a loopback for an Ethernet interface by using the U2000 Web LCT. The Ethernet interface loopback is a common fault location method used to test and maintain the Ethernet board. The Ethernet interface loopback is used to test the fiber connections on the Ethernet board, physical and MAC layers of the Ethernet interface, and SDH layer (that is, the line).
